Is she truly ready for a proposal? Will I regret making such a step?

Her parents asking me why is it that I haven't proposed to their daughter and if I'm just wasting years of her life.


We've been together for 3yrs and it's been some good time we had but I can't help but think how many times she got angry and cut me off for the silliest reasons. This girl got pregnant and terminated it because she was trying to "get back at me" for going on that work trip with my female boss. I can't talk to a female or even laugh with a coworker of the opposite sex. I love her like crazy I really do but I don't want to get myself in a trap either.
